Rear Interfaces
You can use port 1 (wancom1) or port 2 (wancom2) as interfaces to support HA. Do not use port 0 (wancom 0) as that port is reserved for carrying management traffic.
Make sure that the physical connections you have made on the rear panel of your Oracle® Enterprise Session Border Controllers correspond to the configurations you enter for phy-interfaces. You can connect Oracle® Enterprise Session Border Controllers through multiple rear interfaces. For multiple rear interface connectivity, cable both port 1 and port 2 (wancom1 and wancom2) on one Oracle® Enterprise Session Border Controller to port1 and port 2 on the other Oracle® Enterprise Session Border Controller in the HA node.
The Oracle® Enterprise Session Border Controller’s HA function depends heavily on health scores to determine the active and standby roles in an HA node. You can set the amount that will be subtracted from a Oracle® Enterprise Session Border Controller’s health score in the event that a management interface fails for any reason. For example, a connection might become invalid or a cable might be removed inadvertently.
The following example shows how a configured phy-interface will appear in the ACLI for an HA node:
phy-interface name wancom1 operation-type Control port 1 slot 0 virtual-mac wancom-health-score 20
